Closes#3291
- Adds redirects based on roles as defined in the case
- Adds new mixin `CurrentUserSettings`
- For authors, all settings pages redirect to `users/self`
- For editors, all settings pages other than specific users redirect to `users`. Any user that is not self or an author redirects to `users`
